    STI X Comp ATR Radial Tire

    Wayne in OH

    They're just what I wanted.

    Don't know how they are going to hold up but they look great and ride really good compared to the factory set. I can actually hear the radio as I'm going down the road and they're smooth riding on the road as well time will tell how they do on the trails.

  • STI Sand Drifter Front Sand Tire

    STI Sand Drifter Front Sand Tire

    tony in OR

    Best bang for the buck when it comes to sand fronts.

    these bad boys cut hard even in 2wd. Couldn’t be happier. Keeps up with the guys running tributes and 4x4 without s problem and it’s much easier on the belt.
